Last week I attended a conference on the science of consciousness in Helsinki. While there, I attended a very interesting session on the Minimally Conscious State (MCS). This is a state that follows severe brain damage. Those diagnosed as MCS are thought to have some kind of conscious mental life, unlike those in Vegetative State. If that is right – so say many bioethicists and scientists – then the moral implications are profound. But what kind of conscious mental life is a minimally conscious mental life? What kind of evidence can we muster for an answer to this question? And what is the moral significance of whatever answer we favor? One takeaway from the session (for me, at least): it’s complicated.

Last week the Federal Government announced that there would be a review of Australia’s tissue and organ transplantation systems. The impetus for the review appears to be continually disappointing donation rates, despite the adoption of a national reform agenda in 2008.
Since 2008 there has been an increase from 12.1 dpmp (donations per million population) to a peak of 16.9 in 2013 – but the dip last year (to 16.1) indicates that new policies need to be considered if rates are to be substantially increased.
Australia’s donation levels remain considerably below world’s best practice, even after adjusting for rates and types of mortality. At least twenty countries achieve better donation rates than Australia, including comparable countries like Belgium (29.9), USA (25.9), France (25.5) and the UK (20.8).
The review will focus in particular on the role of the national Organ and Tissue Authority, which helps coordinate donation services. However, many of the key policy settings are in the hands of state and territory governments.
It is time to go beyond improving the mechanisms for implementing existing laws, and to consider more fundamental changes to organ procurement in Australia.

According to the NHS, the number of hospital admissions across the UK for teenagers with eating disorders has nearly doubled in the last three years. In a previous post, we discussed some ethical issues relating to the use of deep brain stimulation (DBS) to treat anorexia nervosa (AN). Although the trials of this potential treatment are still in very early, investigational stages (and may not necessarily become an approved treatment), the invasive nature of the intervention and the vulnerability of the potential patients are such that anticipatory ethical analysis is warranted. In this post, we show how different possible mechanisms of intervention raise different questions for philosophers to address. The prospect of intervening directly in the brain prompts exploration of the relationships between a patient’s various mental phenomena, autonomy and identity. Continue reading

How should bioethical discussion be? The academic debate entails a tension between different parties, which often are difficult to compare. To mention some, for example, some draw from the tradition of liberal consequentialism and demand for rationalism and the avoidance of lofty moral arguments. Others descend from the teleological and communitarian tradition, emphasizing that the moral issues ought to be holistically confronted in their complexity, accepting that they cannot be analyzed in logical, reasonable fragments.

The Court of Protection is due to review very soon the case of a teenager with a relapsed brain tumour. The young man had been diagnosed with the tumour as a baby, but it has apparently come back and spread so that according to his neurosurgeon he has been “going in and out of a coma”. In February, the court heard from medical specialists that he was expected to die within two weeks, and authorized doctors to withhold chemotherapy, neurosurgery and other invasive treatments, against the wishes of the boy’s parents.
However, three months after that ruling, the teenager is still alive, and so the court has been asked to review its decision. What should we make of this case? Were doctors and the court wrong?
Let us suppose we have a treatment and we want to find out if it works. Call this treatment drug X. While we have observational data that it works—that is, patients say it works or, that it appears to work given certain tests—observational data can be misleading. As Edzard Ernst writes:
Whenever a patient or a group of patients receive a medical treatment and subsequently experience improvements, we automatically assume that the improvement was caused by the intervention. This logical fallacy can be very misleading […] Of course, it could be the treatment—but there are many other possibilities as well. Continue reading
Many important discussions in practical ethics necessarily involve a degree of speculation about technology: the identification and analysis of ethical, social and legal issues is most usefully done in advance, to make sure that ethically-informed policy decisions do not lag behind technological development. Correspondingly, a move towards so-called ‘anticipatory ethics’ is often lauded as commendably vigilant, and to a certain extent this is justified. But, obviously, there are limits to how much ethicists – and even scientists, engineers and other innovators – can know about the actual characteristics of a freshly emerging or potential technology – precisely what mechanisms it will employ, what benefits it will confer and what risks it will pose, amongst other things. Quite simply, the less known about the technology, the more speculation has to occur.
In practical ethics discussions, we often find phrases such as ‘In the future there could be a technology that…’ or ‘We can imagine an extension of this technology so that…’, and ethical analysis is then carried out in relation to such prognoses. Sometimes these discussions are conducted with a slight discomfort at the extent to which features of the technological examples are imagined or extrapolated beyond current development – discomfort relating to the ability of ethicists to predict correctly the precise way technology will develop, and corresponding reservation about the value of any conclusions that emerge from discussion of, as yet, merely hypothetical innovation. A degree of hesitation in relation to very far-reaching speculation indeed seems justified. Continue reading
In a recent issue of the Journal of Medical Ethics, Thomas Ploug and Søren Holm point out that scientific communities can sometimes get pretty polarized. This happens when two different groups of researchers consistently argue for (more or less) opposite positions on some hot-button empirical issue.
The examples they give are: debates over the merits of breast cancer screening and the advisability of prescribing statins to people at low risk of heart disease. Other examples come easily to mind. The one that pops into my head is the debate over the health benefits vs. risks of male circumcision—which I’ve covered in some detail here, here, here, here, and here.
When I first starting writing about this issue, I was pretty “polarized” myself. But I’ve tried to step back over the years to look for middle ground. Once you realize that your arguments are getting too one-sided, it’s hard to go on producing them without making some adjustments. At least, it is without losing credibility — and no small measure of self-respect.
This point will become important later on.
Nota bene! According to Ploug and Holm, disagreement is not the same as polarization. Instead, polarization only happens when researchers:
(1) Begin to self-identify as proponents of a particular position that needs to be strongly defended beyond what is supported by the data, and
(2) Begin to discount arguments and data that would normally be taken as important in a scientific debate.
But wait a minute. Isn’t there something peculiar about point number (1)?
On the one hand, it’s framed in terms of self-identification, so: “I see myself as a proponent of a particular position that needs to be strongly defended.” Ok, that much makes sense. But then it makes it sound like this position-defending has to go “beyond what is supported by the data.”
But who would self-identify as someone who makes inadequately supported arguments?
We might chalk this up to ambiguous phrasing. Maybe the authors mean that (in order for polarization to be diagnosed) researchers have to self-identify as “proponents of a particular position,” while the part about “beyond the data” is what an objective third-party would say about the researchers (even if that’s not what they would say about themselves). It’s hard to know for sure.
But the issue of self-identification is going to come up again in a minute, because I think it poses a big problem for Ploug and Holm’s ultimate proposal for how to combat polarization. To see why, though, I have to say a little bit more about what their overall suggestion is in the first place.
Press Release: The moral imperative to research editing embryos: The need to modify Nature and Science
The first study in which the DNA of human embryos was intentionally modified has been published in the journal Protein & Cell, released on Saturday. This research is significant because it may be an important step toward a world where we are free from genetic disease. However allegations that Nature and Science refused to publish this research on ethical grounds are concerning.
The Director of the Oxford Uehiro Centre for Practical Ethics Professor Julian Savulescu has called on Nature and Science to clearly explain their editorial decisions in relation this study.
“If these studies were rejected for ethical reasons we need to know what these reasons are.” Professor Savulescu said.
“There was absolutely no potential for this research to directly result in the birth of a modified human and it is unclear how the study could have harmed or wronged anyone.
Nature should explain why it deems this research ethically problematic, and yet publishes other controversial research, involving viruses, with the potential to directly kill millions of people.” Continue reading
